No database revisioning

[mxmeinhold]

Currently, if a change is made to the database schema, a user with administrative access must go in and manually make the changes.

It’d be cool if we had a tool like Alembic to manage db revisions. This has a couple of really handy features:

• Tracked revisions
• Easily managed upgrades and downgrades
• Easy provisioning of testing instances.

Any revision files would need to be mirrored to https://github.com/ComputerScienceHouse/QuotefaultAPI to make sure they stay in sync.
